Ampelocissus latifolia (Roxb.) Planch. (Family: Vitaceae), native to Indian subcontinent is used extensively for its

uvaribonin and chalcone isolated from the root of Phillippine Ampelocissus showed significant cell growth

The use of synthetic chemicals for controlling unwanted herbs or weeds is one of the most effective methods.
Indiscriminate use of synthetic chemicals is continuously being phased out because of their adverse effects on the
environment. As a result, the use of plant secondary metabolites as herbicide or weedicide is gaining renewed
interest. At the present state of knowledge allelopathic activities of A. latifolia are not studied. Hence, the objective
